Amazfit has officially begun the rollout of its latest software enhancement, firmware version 6.7.0.1, specifically tailored for the Amazfit Active 2. This update isn’t just a minor patch; it introduces significant rebranding of core health metrics and expands the device’s compatibility with professional-grade fitness tools, making it a much more formidable companion for serious athletes.
From Readiness to BioCharge: A New Health Paradigm

The most visible change in this update is the evolution of the “Readiness” score into the new BioCharge feature. While the core goal remains the same—helping users understand how recovered their bodies are—BioCharge aims to provide a more holistic view of physical energy and recovery levels. This transition reflects Amazfit’s shift toward a more dynamic and actionable health monitoring system.
Seamless Integration with Pro-Level Training Platforms
For fitness enthusiasts who rely on external coaching and data analysis, this update is a game-changer. The Amazfit Active 2 now supports third-party workout plan syncing from industry leaders TrainingPeaks and Intervals.icu. This means users can now follow complex, structured training schedules directly from their wrist without manual entry or constant phone checking.
Enhanced Precision for Runners and Power Athletes
In a move that will delight the running community, the device now supports connections to Stryd running power meters. By integrating with Stryd, the Active 2 can now provide advanced power metrics, helping runners gauge their efficiency and intensity more accurately than heart rate alone. Additionally, Amazfit has refined its Sleep Score algorithm, ensuring that the data captured overnight is more precise and representative of actual rest quality.
Streamlined Navigation and System Enhancements
Beyond the fitness upgrades, the firmware introduces a practical UI improvement: double-press shortcuts for the lower physical button. Users can now assign specific functions to this gesture, allowing for faster access to favorite apps or tools. This, combined with various under-the-hood system optimizations, ensures a smoother and more responsive user experience across the board.
Phased Rollout and Global Availability
As is standard with major Zepp OS improvements, this update is being released in phased batches. While a segment of the user base has already reported receiving the 6.7.0.1 notification, others may need to wait a few more days for the software to appear in their region. Users are encouraged to check the “System Update” section within the Zepp app periodically to download and install the latest features as they become available.
